Abstract
The utility model relates to a bolt locating pin with a tungsten disulfide surface coating. The bolt locating pin comprises a locating pin main body that comprises a head part and a tail part; the head part is connected with the tail part; the bolt locating pin is characterized in that the tungsten disulfide surface coating is arranged on the locating pin main body; the surface coating has the thickness being 5-7mm; and a gasket is arranged between the head part and the tail part. The tungsten disulfide surface coating has excellent wear resistance and antifriction property, so that the friction loss between the locating pin and a workpiece is greatly reduced, the work stability of the locating pin is guaranteed, the service life is prolonged, and the bolt locating pin is safe and environment-friendly.
Description
Technical field
The utility model relates to a kind of locating stud, is specifically related to have the bolt locating stud of tungsten disulfide cover coat, belongs to the technical field of mechanical parts.
Background technique
Detachable or the adjustable locating stud part of a large amount of employings in the assembly tooling.In the existing technology, being decided to be pin is a kind of polished rod class locating stud.Wearing no resistance between the workpiece that locating stud and band are fixed, the also abrasion easily between locating stud and the workpiece, thereby the working life of locating stud is not long.
The model utility content
The purpose of the utility model is, the locating stud of the bolt with tungsten disulfide cover coat is provided, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
The technical problem of the required solution of the utility model, can realize through following technological scheme:
Have the bolt locating stud of tungsten disulfide cover coat, comprising: the locating stud main body, said locating stud main body comprises: head, afterbody, head is connected with afterbody, it is characterized in that, the cover coat of tungsten disulfide is set on the said locating stud main body.
Wherein, the thickness of said cover coat is 5～7mm.
Wherein, the thickness of said cover coat is 5mm.
Wherein, between said head and the afterbody pad is set.
Wherein, the width of said head is less than the width of afterbody.
The beneficial effect of the utility model:
The utility model adopts tungsten disulfide WS
2Cover coat reduce friction factor, reduce wear, interlock etc.Overcome or reduce the mechanical lubrication problem, improve the working efficiency and the working life of machinery.Specifically can eliminate or reduce many device maintenance, the maintenance issues that causes by friction, abrasion etc.The application life of locating stud has prolonged 2～3 times.
Normal loading reaches 100,000PSI (or identical with the bearing capacity of base material).
Operating temperature range is wide, from-273 ℃ to 60.50 ℃.
There are not any harmful components, safety and environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Reference character:
Locating stud main body 100, head 110, afterbody 120, pad 130, workpiece 300 and cover coat 400.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
The experimental technique of unreceipted actual conditions in the following example, usually according to normal condition, or the condition that manufacturer provides is carried out.
Embodiment 1
Have the bolt locating stud of tungsten disulfide cover coat, as shown in Figure 1, comprising: locating stud main body 100.Locating stud main body 100 comprises: head 110, afterbody 120 and pad 130.Head 110 is connected with afterbody 120.Between head 110 and the afterbody 120 pad 130 is set.
The width of head 110 is less than the width of afterbody 120.Be that afterbody 120 expands than head 110, be convenient to the location of bolt locating stud, like convenient rotation.The striped that increases friction or protruding also can be set on the afterbody 120, this not accompanying drawing illustrate.
The cover coat of tungsten disulfide is set on the locating stud main body 100.
The thickness of cover coat 400 is 5～7mm.Cover coat 400 preferred thickness are 5mm.
The preparation process and method of the utility model:
Locating stud main body 100 or head 110 are through the ultrasonic cleaning oil removing; With MEVVA source ion injection technique (metal vapor vacuum arc source technology), TiN is attached to the die steel surface subsequently, forms the lubricating film base layer; Layer thickness is 0.005 μ m; On the coating of TiN base, the radio-frequency sputtering mode with in the physical gas phase deposition technology is covered with tungsten disulfide WS then
2Coating, layer thickness are 0.5 μ m.The die steel of the band lubricating layer that obtains has the characteristic of TiN hardness height and favorable anti-corrosion effect; With tungsten disulfide WS
2Low coefficient of friction, greasy property is high, resistant to elevated temperatures comprehensive function.Be suitable for the surface treatment and the processing and fabricating of month various moulds, mechanical part, auto parts and components.
Adopt cover coat (tungsten disulfide WS
2) to the surface treatment treatment technology of locating stud main body 100, effectively improved the high temperature of locating stud main body 100 and prevented killing performance, and then prolonged the working life of locating stud main body 100.
Adopt tungsten disulfide WS
2The surface treatment treatment technology carries out WS with locating stud main body 100
2Handle, effectively improved the high temperature of locating stud and prevented killing performance, and then prolonged the working life of locating stud.
Tungsten disulfide WS
2Why show good lubricating property and be because: WS
2Crystal has stratiform structure, layer with layer between combination force a little less than, shear easily, slippage, show as low friction coefficient; WS
2Structural stability shows as good resistance high temperature, resistance to extreme pressure ability; Even be higher than under 400 ℃ the temperature environment WS
2Also can form fine and close tungsten oxide (WO through eremacarsis
3) protective layer, suppress WS
2Further oxidation, and tungsten oxide has very low friction factor equally, still can play the effect that the protective money metal surface does not glue together.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
